“…Also, the work in [9] only mentions biased node capture attacks, while we discuss biased node capture attacks and design countermeasures against them in this paper. In [10], a key management scheme is proposed, wherein sensor nodes are organized into multiple hierarchies using a tree structure. Three types of keys are provisioned initially.…”

“…In our scheme, we do not use different cluster head keys, but rather use same key pools that reduces complexity during key predistribution and subsequent pair-wise set-up. Also, the scheme in [10] suffers from poor resilience under node compromises and all keys have to be refreshed very quickly. In [11], a new protocol for cluster-head selection is proposed, and ideas are proposed for key additions and revocations under network dynamics via one-way hash functions.…”

Abstract-In many Wireless Sensor Networks (WSNs), providing end to end secure communications between sensors and the sink is important for secure network management. While there have been many works devoted to hop by hop secure communications, the issue of end to end secure communications is largely ignored. In this paper, we design an end to end secure communication protocol in randomly deployed WSNs. Specifically, our protocol is based on a methodology called differentiated key pre-distribution. The core idea is to distribute different number of keys to different sensors to enhance the resilience of certain links. This feature is leveraged during routing, where nodes route through those links with higher resilience. Using rigorous theoretical analysis, we derive an expression for the quality of end to end secure communications, and use it to determine optimum protocol parameters. Extensive performance evaluation illustrates that our solutions can provide highly secure communications between sensor nodes and the sink in randomly deployed WSNs. We also provide detailed discussion on a potential attack (i.e. biased node capturing attack) to our solutions, and propose several countermeasures to this attack.

“…In this approach, two communicating nodes contact their network manager or cluster head to discover a shared generation key between them for secret key generation. Node addition and revocation capability were introduced by Poornima and Amberker [28] in a tree-based key management scheme while unpredictable software-based attestation solution (USAS) is presented in [29] to detect the compromised node in the network.…”

Advancement in wireless sensor network (WSN) technology makes it more attractive technology to be adopted in real world applications including home and industrial automation and e-health or infrastructure monitoring. However the mobility consideration in these applications makes the security requirements an essential and challenging task. To make the communication secure and the network robust against attacks, a proper key management scheme should be used. This paper presents a secure online key establishment and authentication scheme for mobility supported heterogeneous sensor networks. The performance evaluation of the proposed scheme is done using OMNET++ simulator while AVISPA tool is used to validate the security of the proposed scheme. It is clear from the obtained results that the proposed scheme provides better network connectivity at a low cost of memory occupation and communication overhead during the authentication and key establishment phases while improving its network resilience against attacks.

Improving Key Management Scheme Supporting Node Mobility in Heterogeneous Sensor Networks using Collision-Keys

Wireless Sensor Networks (WSNs) consist of a large number of sensor nodes that are batteries powered, equipped with limited memory and computational capabilities. These constrained devices face many security threats and thus there is a need of some cryptographic mechanism for secure communication. Key distribution is of critical importance to provide security in WSNs. Till now a number of key distribution schemes are proposed in the literature but there are very few schemes considering mobility of sensor nodes. In this paper we have proposed a modification to the key management scheme supporting node mobility in heterogeneous sensor network. Our modification uses Hash collision keys to improve the network resilience and connectivity between the nodes. We have evaluated our scheme analytically and obtained results show that our proposed solution assures better network connectivity and resilience while increasing an insignificant computational overhead.
